Abstract
A vehicle drive force control method according to the present invention includes calculating an estimated friction circle on the basis of longitudinal and lateral accelerations of a vehicle, limiting a drive force of the vehicle depending on a size of the estimated friction circle, and limiting a change rate of the size of the estimated friction circle during vehicle traveling on the basis of a tire generation force. The method further the change rate as the tire generation force increases.
